Bahamut is a regular character in the Final Fantasy series. He is a large dragon whose appearance varies depending on game. Bahamut often appears as a summonable creature. Its signature attack is generally Mega Flare, in which he issues a massive blast of energy.

Bahamut - A grey/black dragon who performs the Mega Flare attack, his summon materia is found in the Temple of the Ancients after defeating the Red Dragon.

Neo Bahamut - A red/yellow dragon who performs the Giga Flare attack, his summon materia is found in the Northern Crater of the FF7 World Map, during your first visit.

Bahamut ZERO - A six-winged, teal/grey dragon who performs the Terra Flare attack, his summon materia is obtained by touching the blue huge materia after having collected both the Bahamut and Neo Bahamut materia beforehand.

Bahamut is one of the more powerful GFs in the game. He is found in the Deep Sea Research Center where you must battle and defeat him to acquire him. His attack Mega Flare is ideal because it is non-elemental and does massive damage. Bahamut also learns very useful abilities such as Rare Item (raises the chance of rare items being dropped by monsters), Mug, Auto-Protect, and the ability to refine items into the strongest magic in the game.

Bahamut is originally one of Princess Garnet's Eidelons, but is extracted from her by Queen Brahne early in the game. Brahne later summons him at the Iifa Tree to attack Kuja, but Kuja uses the Invincible to capture him and use him to attack Alexandria. He is defeated after Garnet and Eiko summon Alexander to protect the city. Garnet can learn to summon Bahamut from the Garnet item given to the party by Beatrix. Bahumut has a non-elemental attack but can deal a huge amount of damage to your enemy.

Bahamut appears in Dissidia in both Auto and Manual summonstones. His Auto summon is modeled after the Final Fantasy X version, while the Manual summon is modeled after the Final Fantasy V version. The Manual summon effect lasts longer than the Auto summon.
